Abstract

A tow bar system for coupling a bicycle to a wheeled trolley is provided. The tow bar system includes a first portion, a second portion, a trailer arm and a wheel. The first portion is configured to be removably coupled to the bicycle. The second portion is configured to be removably coupled to the wheeled trolley. The trailer arm extends between the first and second portions and at least a portion of the trailer arm having a substantially arc shape to avoid contact with the bicycle. The wheel is coupled to at least one of the second portion and the trailer arm

         3 . The tow bar system of  claim 2  wherein the first pivot is a universal joint. 
     
     
         4 . The tow bar system of  claim 1  further comprising a second pivot located at the second portion to permit at least a portion of the tow bar system to pivot relative to the wheeled trolley. 
     
     
         5 . The tow bar system of  claim 1  further comprising a suspension. 
     
     
         6 . The tow bar system of  claim 1  wherein the wheel is in a fixed position relative to the trailer arm. 
     
     
         7 . The tow bar system of  claim 1  further comprising a quick release at the first portion to removably couple the tow bar system to the bicycle. 
     
     
         8 . The tow bar system of  claim 1  further comprising at least one clamp at the second portion to removably couple the tow bar system to the wheeled trolley. 
     
     
         9 . The tow bar system of  claim 1  further comprising a mud flap. 
     
     
         10 . A tow bar system for coupling a bicycle to a wheeled trolley, the tow bar system comprising:
 a first portion configured to removably coupled to the bicycle, the first portion including a first pivot to permit at least a portion of the tow bar system to pivot about at least two axes relative to the bicycle;   a second portion configured to be removably coupled to the wheeled trolley; and   a trailer arm extending between the first and second portions, at least a portion of the trailer arm having a substantially arc shape to avoid contact with the bicycle.   
     
     
         11 . The tow bar system of  claim 10  further comprising a wheel coupled to at least one of the second portion and the trailer arm. 
     
     
         12 . The tow bar system of  claim 10  wherein the first pivot is a universal joint. 
     
     
         13 . The tow bar system of  claim 10  further comprising a second pivot located at the second portion to permit at least a portion of the tow bar system to pivot relative to the wheeled trolley. 
     
     
         14 . The tow bar system of  claim 10  further comprising a suspension. 
     
     
         15 . The tow bar system of  claim 10  wherein the wheel is in a fixed position relative to the trailer arm. 
     
     
         16 . The tow bar system of  claim 10  further comprising a quick release at the first portion to removably couple the tow bar system to the bicycle. 
     
     
         17 . The tow bar system of  claim 10  further comprising at least one clamp at the second portion to removably couple the tow bar system to the wheeled trolley. 
     
     
         18 . The tow bar system of  claim 10  further comprising a mud flap.
